The background selection hypothesis predicts a reduction in nucleotide site diversity and an excess of rare variants, owing to linkage associations with deleterious alleles. This effect is expected to be amplified in species that are predominantly self-fertilizing. To examine the predictions of the background selection hypothesis in self-fertilizing species, we sequenced 1,362 bp of adh1, a gen...

Origanum onites and Origanum vulgare ssp. hirtum were collected from Balikesir, on the north west of Turkey. The nitrogen contents in organs such as root, stem, leaf and flower of Origanum onites and Origanum vulgare ssp. hirtum taxa in vegetative and generative growth stages were investigated. Nitrogen analyses of soil and plant samples were carried out according to the Kjeldahl method. It was...

The protein kinase (PK) superfamily is one of the largest superfamilies in plants and core regulator cellular signaling. Despite this substantial importance, kinomes sugarcane sorghum have not been profiled. Here, we identified profiled complete polyploid Saccharum spontaneum (Ssp) Sorghum bicolor (Sbi), a close diploid relative. Sbi kinome was composed 1,210 PKs; for Ssp, 2,919 PKs when disreg...

Remains of barley (Hordeum vulgare) grains found at archaeological sites in the Fertile Crescent indicate that about 10,000 years ago the crop was domesticated there from its wild relative Hordeum spontaneum. The domestication history of barley is revisited based on the assumptions that DNA markers effectively measure genetic distances and that wild populations are genetically different and the...

The occurrence of an extra-plastidial isoform of ADP-glucose (Glc) pyrophosphorylase (AGPase) among starch-storing organs was investigated in two ways. First, the possibility that an extra-plastidial isoform arose during the domestication of cereals was studied by comparing the intracellular distribution of enzyme activity and protein in developing endosperm of noncultivated Hordeum species wit...

Нашими попередніми дослідженнями встановлена висока стійкість окремих зразків H. spontaneum до популяцій рас гельмінтоспоріозної інфекції південної зони України та характер успадковування цієї стійкості у гібридних поколіннях [8, 9] при цьому використання джерел патогенів в селекції рослин це імунологічний напрям, тоді як звичайний селекційний процес охоплює відразу кілька напрямків оцінювання ...
